You can only learn what obedience is by obeying
Nothing is so at odds with prayer as vanity.
Gratitude changes the pangs of memory into a tranquil joy.
When our will wholeheartedly enters into the prayer of Christ, then we pray correctly.
After he has been following Christ for a long time, the disciple of Jesus will be asked, "Lacked ye anything?" and he will answer "Nothing, Lord." How could he when he knows that despite hunger and nakedness, persecution and danger, the Lord is always at his side?
But the Christian also knows that he not only cannot and dare not be anxious, but that there is no need for him to be so. Neither anxiety now work can secure his daily bread, for bread is the gift of the Father.
